About Us
Courage Therapeutics is a leading neuroendocrine company co-founded by Dr. Roger Cone, a pioneering researcher in melanocortin receptor biology and the central melanocortin system’s neural circuits in the brain. The company is dedicated to translating Dr. Cone’s decades of work and discoveries of novel biological mechanisms of energy homeostasis into novel therapeutic candidates targeting the MC4R and MC3R receptors.
Our Focus
Our MC4R programs focus on treating various genetic obesities as well as addressing dietary obesity in the general population. Activity in various animal models show our compounds have profound monotherapy activity and can also act synergistically with GLP-1s to potently augment their activity and break through their weight loss plateau. Our MC3R program focuses on stimulating food intake with applications in sarcopenia, anorexias and cachexia. Courage Therapeutics is dedicated to developing promising new medicines for these life-threatening diseases.
MC4R Pathway
MC4R is a genetic driver of obesity. Through rectifying insufficient activity of the MC4R pathway that is defective in patients with a number of different genetic obesities, we can correct the genetic defects and augment activity to restore balance and energy homeostasis.
For the broader population suffering from dietary obesity, we seek to overcome challenges for patients where the currently available GL-1 drugs cannot be tolerated, or provide inadequate weight loss for optimal health. Further, muscle mass loss and weight regain upon discontinuation are serious drawbacks for this widespread class of drugs. Our initial results in animals demostrate that when combined with GLP-1s, we achieve more profound weight loss while sparing lean muscle mass and also delaying weight re-gain upon discontinuation of treatment.
MC3R Pathway
Dr. Cone and colleagues have demonstrated that MC3R agonists stimulate food intake, as as also reduce anxiety, suggesting novel utility in multiple eating disorders. We are targeting MC3R to develop therapeutics that have applications in a variety of indications ranging from diseases of wasting such as sarcopenia and cachexia, to more serious disorders such as anorexia nervosa, anorexia of aging and failure-to-thrive in infants.

CEO

Mr. Ferrara was was most recently President and CEO of Medeor Therapeutics, Inc., a transplant immunology company where he completed the world’s first multi-center, international Phase 3 clinical study that successfully induced immunotolerance in transplant patients allowing them to eliminate the use of toxic immunosuppressive drugs. Prior to that, he was Founder, President and CEO of NeuroVia, Incl, a clinical stage orphan CNS disease company, where he raised a Series A financing, built an efficient team and established the clinical and regulatory strategy to lead the company into an efficacy study. Previously, he was an Entrepreneur-in-Residence at Novartis Venture FundS (NVF), where he founded NeuroVia in 2013 amongst his other activities as an operating partner. He joined NVF from portfolio company Sorbent Therapeutics where he was consulting Chief Business Officer, raising $58M in oversubscribed financing and lead the refocusing of the company’s lead program. Prior roles include General Partner and Managing Director at Burrill & Company after starting his venture capital and business development career at GeneChem Management (including CEO of portfolio company Targanta Therapeutics) and BioChem Pharma. He received his MBA and MSc (molecular endorcrinology) from McGill University.
Roger Cone, Ph.D.
Co-Founder

Roger Cone joined the University of Michigan as 2016 as the Director of the Life Sciences Institute, and was appointed Vice Provost for the Biosciences in 2017. Prior to Michigan, Cone was Professor and Chairman of the Department of Molecular Physiology and Biophysics at Vanderbilt University from 2008-2016. Cone is credited with the discovery of multiple fundamental biological roles for the melanocortin system in energy homeostasis. These findings resulted from studies cloning and characterizing the five receptors for the melanocortin peptides, and analyzing the pharmacological and physiological functions of these receptors. Cone’s group provided the genetic and pharmacological validation of the melanocortin-4 and melanocortin-3 receptors as critical regulators of energy homeostasis, leading to the discovery of mutations in the MC4R as the leading cause of syndromic obesity, and development of the first drug for syndromic obesity, the MC4R agonist Imcivree, approved by the FDA in 2020. Cone has been elected to the National Academy of Sciences (2010), and the National Academy of Medicine (2016) for his work, and received numerous awards, including the Berson Award, Berthold Memorial Award, Ipsen Prize, and the Rolf Luft Prize.
